What battery does solar street light use?

Lithium batteries are small, light and easy to transport. Compared with lead-acid colloidal batteries for solar street lights with the same power, the weight is about one third and the volume is about one third. As a result, transportation is easier and transportation costs naturally fall. Lithium batteries have high energy density and long life. Energy density refers to the amount of energy stored in a given space or unit of mass. The higher the energy density of a battery, the more electricity it can store per unit weight or volume. There are many factors that affect the life of lithium batteries, of which energy density is one of the most important internal factors.

Solar street lights use lithium batteries to install easy traditional solar street lights installation, need to reserve a battery pit, the battery into the underground box sealed. The installation of lithium solar street lights is more convenient, and the lithium battery can be directly installed on the bracket, using suspension or built-in. Lithium-ion solar street lights are easy to maintain. Lithium-ion solar street lights only need to take out the battery on the pole or panel during maintenance. Compared with lithium solar street lights produced by lithium battery spot welding machines, traditional solar street lights require more trouble to dig underground batteries for maintenance.

I'm sure everyone is familiar with batteries and knows that they need to be able to store electrical energy. The same is true of batteries for solar LED street lights, which are also used to store electricity and provide lighting. Its types are generally lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries. However, in street lighting, more colloidal lead-acid batteries are used. It can meet the premise of night lighting, store the energy generated by solar energy during the day, and store energy to meet the lighting needs of continuous rainy night lighting.

For the capacity of the battery, if it is too small, it can not meet the needs of night lighting. If the battery capacity is too large, the battery will be in a state of power failure, affecting the service life of the battery, will also cause a certain waste, increase unnecessary costs. The 18650 lithium battery is not a simple whole, it needs to match solar photovoltaic panels and load power. In this way, it can make full use of its functions and provide the storage function of electric energy.

For solar street lights, some of its components, each part is very important, so we must pay attention to it. For the solar street lamp battery, it is the basis for ensuring lighting, so it must be selected and used correctly.
